نتیجه
د وړاندې شوي پوښتنو او د پایلې راپور ورکولو په کارولو سره، تاسو کولی شئ د انفرادي پوښتنو او په ټولیزه توګه د ټول کلستر لپاره د فعالیت د تخریب ستونزې تحلیل او حل کولو لپاره یو بشپړ انځور ترلاسه کړئ.
پرمختیا
تر دې دمه پرمختیایي پلانونه په لاندې ډول دي:
- د بلاک کولو تاریخ سره راپور ورکول بشپړ کړئ. غوښتنلیکونه ازمول کیږي او ډیر ژر به وسپارل شي.
- د pg_stat_activity او pg_locks تاریخ ذخیره کولو لپاره د TimescaleDB توسیع وکاروئ.
- د تولید اډو کې د ډله ایز ګمارلو لپاره په ګیتوب کې د بسته بندۍ حل چمتو کړئ.
